An account in Akuko is the central place that allows you to manage your posts as an organization. Whenever you create a post or source in Akuko they are assigned to an account where you can manage access to them.
In the account management page, simply add the email to the users you want to grant access to your account.
Once added, there are three types of roles you can assign to the user:
Admin - Has ability to add, edit and delete posts and add/delete users to an account.
Editor - Has ability to add, edit and delete posts
